Classic Auto Air adapter mounting plate. As some may know, the CAA evap assembly is only intended for Non-A/C cars and it mounts off the OEM blower fan mounting holes. Well if you have an A/C car and want to upgrade your factory A/C box you're SOL. Why? because the blower fans are completely different between A/C and Non-A/C cars and there's just nothing left to mount the CAA evap box to. Well to solve this issue, I just measured the bejesus out of my stock and CAA evap and firewall and came up with this handy-dandy adapter plate. It has 1/4-20 studs that use 2 of the original stock evap mounting holes and has two open holes to emulate the Non-AC blower fan mounting so that the CAA evap had something to bolt to.
